SPECIFICATION forming part of Letters Patent 'No. 771,337, dated October 4, 19 04.

Application filed October '19, 1903. Serial No. 177,624. (No model.) 7

Be it known that I, JOHN THOMSON, a citizen of the United States, residing in the borough of Manhattan, in the city of New York, in

the county and State of New York, have invented certain new and -useful Improvements in Disk Water-Meters, of which the following is a Specification.

I This invention relates to disk water-meters, and has for its object to increase the sensibility'of registration at low rates of flow, to

increase the endurance when operated at high rates of delivery, to minimize the damage, ex-

" pense, and inconvenience should the meter be meter.

In thedrawings, Figure 1 is an end elevation from the outlet-spud, showing the external contour of the meter in full lines. Fig. 2

is a viev'v similar to that of Fig. 1, but having.

inyinveution.

First. One feature of my invention relates to an improved disposal and construction of the main casings and the disk-casing to reduce the liability to injury inevent of freezing. In this connection reference may be had to my Patent No. 520,197, beginning at page 2, line 70,-and also to my Patent N 0. 602,377.

These patents cover, broadly, a design of meter in which vwhen an inclosing head at the bottom is blown out by the expansive action of freezing the inner measuring-case shall be free to follow the head and also toseparate in two parts horizontally. y In this'wise-the moving column of, ice .within the main casing acting against cited .the inclosing head is at the bottom di-" rectly underneath and in close proximity to the. measuring-chamber, the consequence of which is that these parts are located where the travel of the ice column is greatest. Ac-

cording to the invention herein set forth I.

place the disk-casing inthe lower main cas. (ing and secure it against its seat 10'by the rim 12 of the upper main casing, which acts directly upon the interposed gasket 13,]and in designing the two main casings so that the depth of each shall be approximately equal to the other.

I then secure the two casings to each other by means of bolts or nuts, as 1;

15, arranged by predetermined experiments to break, strip, automatically withdraw,'or yield resiliently under a pressure considerably greater than that which the meter will ordinarily be subjected to, butwell within the strength of the casings, one form of. such nuts or bolts being shown in an application filed by me October 19,1903, Serial No. 117,623, and having slots .15; The conse, quence of this arrangement and disposal If; that the ice will be caused to flow in two directions-that is, from the top downwardly to the line of separation of thc jnain casings and from thev bottom up to the same'line of v Separation. I will now explain the general features of' Thus the two main casings will be forced apart, the contained disk-chamber casing will be lifted from its seat, and its two to an extent equal only to that of. the expansion of the ice in the lower main casing. It is thus less liable to be cramped in its hear- 'ing and can be more easily and surely reset to its normalposition.

Second. Another: feature of my invention Therefore when'the relates to the flow through the casings and v the strainer.

5.) The inflowing Water is caused to pass into the semicircular chamber by the rib or wall 21, thence downwardly through the semicircular strainer 22, situated below the diskcasing, thence across the inner space 23 through the flattened portion 24' of thestrainer,

,through the opening 24 into the opposite semicircular chamber 25, next to the inletport 26, into and around the disk-chamber, and ,finally discharges through the outlet-port 2'2. he strainer is preferably made with :relatively eoarse openings in the portion 22 and smalleropenings in the portion 24. In this wise foreign material of large caliber is re: tained in the outer chamber and material of smaller caliber, in the intermediatcchamber.

favorable manner and with the least impact,

upon the disk and its ball.

Third. Another feature relates'to the con- .trolof the oscillating action of the disk and to. the means of transmitting its motion to the gear-train. These features are shown in Figs. 3 and The disk I is maintained in contact with the conical frustutns '1' .s' of the disk-casing by the spindle 28"operating above and below the ball 29 in the circular grooves 30 31, form'ed in the sockets 32 33. Themotion of l disk is transmitted to the primary pinion of the gear-train hythc lower end of its spindle; 35, which engages the circular groove 35, formed in theball.

the groove'in'the ball gyrates, thereby causing the pinion-spindle to revolve. The'form of I v s thatof the section of a cone, as seen in Fig.7. vIn this'wise the spindle and its pinion aredrivcu equally from both sides of opposite diameters, and thus does not impose (Illustrated in Figs. 2, 3, 4, and- --in, by thus directing the flow the Water,

J g Thus the groovesin the socket in which the ends of the clisl' '-spin(lle gyrate are stationary, whereas ,the end "36o the pinion-spindle to obtainthe case may be.

operate in a bearing-piece 39. having a corresponding number of slots. This bearing-piece is' preferably situated within the bounds of the inlet-port in an open slot 39" in the perimeter of. the disk-casing, the outer surfaces being flush. Hence when the disk-casing is inserted to its seat the bearing-piece is locked to place. Theobject of this construction is to provide in small compass a bearing having a large surface whereby to enduringly resist the high speed and considerable thr'ust-pressure which the action of the disk imposes.

In this wise, too, the spindle is caused simply to rock axially Within its bearing in the disk instead of making a number of complete revolutions, as in the instance of using a :-pindle having a round head acting as a roller in a single slot. The practical advantage thus derived is very important. and the hearing may be readily'applied in meters of various sizes tr, meet the most severe conditions of operation- Fifth. Another feature relates to the geartrain and consists in forming upon the top-of the dislvchamber casinga finished circular planesurface 40 and a similar finished plane surface 41 upon the inner head-of the upper main casing and making the spindles a2 43 otthe geartrain without any shoulders, so that they cannot hear uponthe gear-plates-M 45. Thus when the meter is assembled the ends of the gear-spindles will bear upon either the upper or the lower plane surfaces 40 4:1, as the The consequence of this is to obtain the least, possible friction--that is, pivot-frictionand by the most simple and enduring means.

Sixth. Another feature relates to the stuffing-box and its spindle. The stuifinghox nut proper, 46, Figs. 3 and 8, which compresses the packing material, as 4-7. is par .w of the usual construction. except that it in itself carries an additional nut 48, screwed to its upper end, and i provided with an innenrecess 4=9.. Then the stufling-box spindle is formed with a collar 51, adapted to operate within this recess, the lower end of the spin- Idlc having a flattened portion 52 adapted to engage the slot 53 of the final gear of the train. In this manner it will he observed that 'the outward thrust upon the spindlethat due to the internal pressure of the water is resisted outside of the pressure-chamher and in a recess which is readily capable of being lubricated. Again, by unscrewing the upper nut 4:8 the spindle maiy be withdrawn, and the degree of friction produced by compressing the packing may be manually tested. So,

tic

toofthe downward thrust upon the spindle when app ying the change-gear 54, which connects with the register, is taken upon the of indication this feature is of great importance in that it enables the operator to know with certainty whetherthe packing has been suitably applied to obtain a water-tight joint' 'with the least possible resistance to the revolution of the spindle.

In the claims hereinafter following I use the term yielding to include all sorts of yielding or bending; deflection and retroac-' will separate, causing the ice to flow in two directions and carrying the disk-casing in separated sections, with one of the flowing ice volumes, substantially as and for the purpose set forth. i
